| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| CVE-2026-86144 | High | 2026-09-05 | Not applicable | No public exploit | In xinclude in libxml2 before 2.15.4, xmlXIncludeProcess and xmlXIncludeProcessTree do not propagate parseFlags. This has security relevance for, for example, the XML_PARSE_NONET flag, if (without it) a custom resource loader accesses the internet and triggers XML external entity injection, SSRF, or a denial of service (e.g., for an attacker-controlled internet resource that is intentionally slow). |
| CVE-2026-86143 | High | 2026-09-05 | Not applicable | No public exploit | In xmlIO in libxml2 before 2.15.4, an inconsistency in xmlOutputWriteCallback and xmlBufUse causes negative lengths to reach write callbacks, aka a lack of a check for integer overflow before calling writecallback. This has security relevance for many types of uses of that length value within a callback. |
| CVE-2026-86142 | High | 2026-09-05 | Not applicable | No public exploit | In libxml2 before 2.15.4, there is a heap-based buffer overflow in xmlXPtrEvalXPtrPart because of xmlXPtrEval xpointer length saturation. |
| CVE-2026-86141 | Low | 2026-09-05 | Not applicable | No public exploit | xmlregexp in libxml2 before 2.15.4 has a NULL pointer dereference in xmlRegNewParserCtxt after a strdup failure, i.e., it does not calculate a string length after NULL checking. |
| CVE-2026-86140 | High | 2026-09-05 | Not applicable | No public exploit | In libxml2 before 2.15.4, xmlSnprintfElements in valid.c has a strcat stack-based buffer overflow. |
| CVE-2026-86139 | High | 2026-09-05 | Not applicable | No public exploit | In libxml2 before 2.15.4, xmlURIEscapeStr in uri.c has an integer overflow. |
| CVE-2026-86138 | High | 2026-09-05 | Not applicable | No public exploit | In libxml2 before 2.15.4, xmlDictAddQString in dict.c has an integer overflow and resultant heap-based buffer overflow. |
| CVE-2026-86137 | Medium | 2026-09-05 | Not applicable | No public exploit | In libxml2 before 2.15.4, xmlFAParsePosCharGroup has an out-of-bounds read, aka an out-of-bounds read in the NXT macro in xmlregexp. |
| CVE-2026-11979 | Low | 2026-06-29 | Not applicable | No public exploit | libxml2 is vulnerable to multiple stack-based buffer overflows in the xmlcatalog utility when running in --shell mode. The usershell() function processes user input using fixed-size stack buffers without proper bounds checking. By supplying an overly long input line, an attacker can overflow internal buffers (command, arg, and argv) during input parsing. This results in memory corruption within the stack frame. Successful exploitation may cause a crash or potentially allow arbitrary code execution in the context of the xmlcatalog process. This issue has been fixed in the commit c2e233fc. NOTE: The maintainers of this project did not agree that this issue is a vulnerability and considered it a bug. |
| CVE-2026-6653 | High | 2026-06-22 | Not applicable | No public exploit | Use After Free in libxml2's xmlParseInternalSubset from GNOME libxml2 version 2.9.11 to 2.11.0 allows a remote attacker to cause a denial-of-service via maliciously crafted XML input with improper entity resolution handling. |
| CVE-2026-6732 | High | 2026-04-23 | Not applicable | No public exploit | A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable. |
| CVE-2026-0992 | Low | 2026-01-15 | Not applicable | No public exploit | A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated <nextCatalog> elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition. |
| CVE-2026-0990 | Medium | 2026-01-15 | Not applicable | No public exploit | A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications. |
| CVE-2026-0989 | Low | 2026-01-15 | Not applicable | No public exploit | A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk. |
| CVE-2025-9714 | Medium | 2025-09-10 | Not applicable | No public exploit | Uncontrolled recursion in XPath evaluation in libxml2 up to and including version 2.9.14 allows a local attacker to cause a stack overflow via crafted expressions. XPath processing functions `xmlXPathRunEval`, `xmlXPathCtxtCompile`, and `xmlXPathEvalExpr` were resetting recursion depth to zero before making potentially recursive calls. When such functions were called recursively this could allow for uncontrolled recursion and lead to a stack overflow. These functions now preserve recursion depth across recursive calls, allowing recursion depth to be controlled. |
| CVE-2025-8732 | Low | 2025-08-08 | Not applicable | No public exploit | A vulnerability was found in libxml2 up to 2.14.5. It has been declared as problematic. This vulnerability affects the function xmlParseSGMLCatalog of the component xmlcatalog. The manipulation leads to uncontrolled recursion. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The code maintainer explains, that "[t]he issue can only be triggered with untrusted SGML catalogs and it makes absolutely no sense to use untrusted catalogs. I also doubt that anyone is still using SGML catalogs at all." |
| CVE-2025-6170 | Low | 2025-06-16 | Not applicable | No public exploit | A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections. |
| CVE-2025-32415 | High | 2025-04-17 | Not applicable | Proof of concept only | In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema with certain identity constraints, or a crafted XML schema must be used. |
| CVE-2025-32414 | High | 2025-04-08 | Not applicable | Proof of concept only | In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and xmlPythonFileReadRaw because of a difference between bytes and characters. |
| CVE-2025-27113 | High | 2025-02-18 | Not applicable | No public exploit | libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a NULL pointer dereference in xmlPatMatch in pattern.c. |
| CVE-2022-49043 | High | 2025-01-26 | Not applicable | No public exploit | xmlXIncludeAddNode in xinclude.c in libxml2 before 2.11.0 has a use-after-free. |
| CVE-2024-34459 | High | 2024-05-14 | Not applicable | Proof of concept only | An issue was discovered in xmllint (from libxml2) before 2.11.8 and 2.12.x before 2.12.7. Formatting error messages with xmllint --htmlout can result in a buffer over-read in xmlHTMLPrintFileContext in xmllint.c. |
| CVE-2024-25062 | High | 2024-02-04 | Not applicable | No public exploit | An issue was discovered in libxml2 before 2.11.7 and 2.12.x before 2.12.5. When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to an xmlValidatePopElement use-after-free. |
| CVE-2023-45322 | Medium | 2023-10-06 | Not applicable | No public exploit | libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails. This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is "I don't think these issues are critical enough to warrant a CVE ID ... because an attacker typically can't control when memory allocations fail." |
| CVE-2023-39615 | Medium | 2023-08-29 | Not applicable | Proof of concept only | Xmlsoft Libxml2 v2.11.0 was discovered to contain an out-of-bounds read via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted XML file. NOTE: the vendor's position is that the product does not support the legacy SAX1 interface with custom callbacks; there is a crash even without crafted input. |
| CVE-2023-29469 | Medium | 2023-04-24 | Not applicable | No public exploit | An issue was discovered in libxml2 before 2.10.4. When hashing empty dict strings in a crafted XML document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic and memory errors, such as a double free. This behavior occurs because there is an attempt to use the first byte of an empty string, and any value is possible (not solely the '\0' value). |
| CVE-2023-28484 | Medium | 2023-04-24 | Not applicable | No public exploit | In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference and subsequently a segfault. This occurs in xmlSchemaFixupComplexType in xmlschemas.c. |
| CVE-2022-40304 | High | 2022-11-23 | Not applicable | Exploited | An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. |
| CVE-2022-40303 | High | 2022-11-23 | Not applicable | Exploited | An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a segmentation fault. |
| CVE-2016-3709 | Medium | 2022-07-28 | Not applicable | No public exploit | Possible cross-site scripting vulnerability in libxml after commit 960f0e2. |
| CVE-2022-29824 | Medium | 2022-05-03 | Not applicable | No public exploit | In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well. |
| CVE-2022-23308 | High | 2022-02-26 | Not applicable | No public exploit | valid.c in libxml2 before 2.9.13 has a use-after-free of ID and IDREF attributes. |
| CVE-2021-3541 | Medium | 2021-07-09 | Not applicable | No public exploit | A flaw was found in libxml2. Exponential entity expansion attack its possible bypassing all existing protection mechanisms and leading to denial of service. |
| CVE-2021-3517 | High | 2021-05-19 | Not applicable | No public exploit | There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application. |
| CVE-2021-3518 | High | 2021-05-18 | Not applicable | No public exploit | There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to confidentiality, integrity, and availability. |
| CVE-2021-3537 | Medium | 2021-05-14 | Not applicable | No public exploit | A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability. |
| CVE-2017-15412 | High | 2018-08-28 | Not applicable | No public exploit | Use after free in libxml2 before 2.9.5, as used in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. |
| CVE-2018-14567 | Medium | 2018-08-16 | Not applicable | No public exploit | libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035 and CVE-2018-9251. |
| CVE-2016-9598 | Medium | 2018-08-16 | Not applicable | No public exploit | libxml2, as used in Red Hat JBoss Core Services, allows context-dependent attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted XML document. NOTE: this vulnerability exists because of a missing fix for CVE-2016-4483. |
| CVE-2016-9596 | Medium | 2018-08-16 | Not applicable | No public exploit | libxml2, as used in Red Hat JBoss Core Services and when in recovery mode, allows context-dependent attackers to cause a denial of service (stack consumption) via a crafted XML document. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-3627. |
| CVE-2016-9597 | High | 2018-07-30 | Not applicable | No public exploit | It was found that Red Hat JBoss Core Services erratum RHSA-2016:2957 for CVE-2016-3705 did not actually include the fix for the issue found in libxml2, making it vulnerable to a Denial of Service attack due to a Stack Overflow. This is a regression CVE for the same issue as CVE-2016-3705. |
| CVE-2018-14404 | Medium | 2018-07-19 | Not applicable | No public exploit | A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case. Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application. |
| CVE-2017-18258 | Medium | 2018-04-08 | Not applicable | No public exploit | The xz_head function in xzlib.c in libxml2 before 2.9.6 allows remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality does not restrict memory usage to what is required for a legitimate file. |
| CVE-2018-9251 | Medium | 2018-04-04 | Not applicable | No public exploit | The xz_decomp function in xzlib.c in libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035. |
| CVE-2017-7376 | Critical | 2018-02-19 | Not applicable | No public exploit | Buffer overflow in libxml2 allows remote attackers to execute arbitrary code by leveraging an incorrect limit for port values when handling redirects. |
| CVE-2017-7375 | Critical | 2018-02-19 | Not applicable | No public exploit | A flaw in libxml2 allows remote XML entity inclusion with default parser flags (i.e., when the caller did not request entity substitution, DTD validation, external DTD subset loading, or default DTD attributes). Depending on the context, this may expose a higher-risk attack surface in libxml2 not usually reachable with default parser flags, and expose content from local files, HTTP, or FTP servers (which might be otherwise unreachable). |
| CVE-2017-5130 | High | 2018-02-07 | Not applicable | No public exploit | An integer overflow in xmlmemory.c in libxml2 before 2.9.5, as used in Google Chrome prior to 62.0.3202.62 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted XML file. |
| CVE-2017-16932 | High | 2017-11-23 | Not applicable | No public exploit | parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities. |
| CVE-2017-16931 | Critical | 2017-11-23 | Not applicable | No public exploit | parser.c in libxml2 before 2.9.5 mishandles parameter-entity references because the NEXTL macro calls the xmlParserHandlePEReference function in the case of a '%' character in a DTD name. |
| CVE-2017-9050 | High | 2017-05-18 | Not applicable | No public exploit | libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictAddString function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for CVE-2016-1839. |
| CVE-2017-9049 | High | 2017-05-18 | Not applicable | Proof of concept only | libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictComputeFastKey function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for libxml2 Bug 759398. |
| CVE-2017-9048 | High | 2017-05-18 | Not applicable | No public exploit | libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based buffer overflow. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size. This vulnerability causes programs that use libxml2, such as PHP, to crash. |
| CVE-2017-9047 | High | 2017-05-18 | Not applicable | No public exploit | A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash. |
| CVE-2017-8872 | Critical | 2017-05-10 | Not applicable | No public exploit | The htmlParseTryOrFinish function in HTMLparser.c in libxml2 2.9.4 allows attackers to cause a denial of service (buffer over-read) or information disclosure. |
| CVE-2017-5969 | Medium | 2017-04-11 | Not applicable | No public exploit | libxml2 2.9.4, when used in recover mode, allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted XML document. NOTE: The maintainer states "I would disagree of a CVE with the Recover parsing option which should only be used for manual recovery at least for XML parser. |
| CVE-2016-4483 | High | 2017-04-11 | Not applicable | No public exploit | The xmlBufAttrSerializeTxtContent function in xmlsave.c in libxml2 allows context-dependent attackers to cause a denial of service (out-of-bounds read and application crash) via a non-UTF-8 attribute value, related to serialization. NOTE: this vulnerability may be a duplicate of CVE-2016-3627. |
| CVE-2016-9318 | Medium | 2016-11-16 | Not applicable | Proof of concept only | libxml2 2.9.4 and earlier, as used in XMLSec 1.2.23 and earlier and other products, does not offer a flag directly indicating that the current document may be read but other files may not be opened, which makes it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document. |
| CVE-2016-4658 | Critical | 2016-09-25 | Not applicable | No public exploit | xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory corruption) via a crafted XML document. |
| CVE-2016-5131 | High | 2016-07-23 | Not applicable | No public exploit | Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function. |
| CVE-2016-4449 | High | 2016-06-09 | Not applicable | No public exploit | XML external entity (XXE) vulnerability in the xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.4, when not in validating mode, allows context-dependent attackers to read arbitrary files or cause a denial of service (resource consumption) via unspecified vectors. |
| CVE-2016-4448 | Critical | 2016-06-09 | Not applicable | No public exploit | Format string vulnerability in libxml2 before 2.9.4 allows attackers to have unspecified impact via format string specifiers in unknown vectors. |
| CVE-2016-4447 | High | 2016-06-09 | Not applicable | No public exploit | The xmlParseElementDecl function in parser.c in libxml2 before 2.9.4 allows context-dependent attackers to cause a denial of service (heap-based buffer underread and application crash) via a crafted file, involving xmlParseName. |
